The working principle of laundry detergent is similar to that of traditional washing powder and soap, and the active ingredients are surfactants. The difference is that the traditional washing powder and soap are made of anionic surfactants, mainly composed of sodium alkyl sulfonate and sodium stearate, which are more alkaline (the PH value of washing powder is generally greater than 12), so it is more irritating and harmful to the skin when used.
Most laundry detergents use nonionic surfactants, and their PH value is close to neutral, which is mild to the skin. After discharged into nature, it degrades faster than washing powder, so it becomes a new generation of detergent.
Washing clothes is the most ordinary thing in life. Washing powder has always occupied the main position in the products used for washing clothes. However, careful people will find that the main component of laundry detergent is nonionic surfactant, which has strong decontamination ability and can go deep into the interior of clothing fibers to play a washing role, and the decontamination is more thorough.
Washing powder can not be completely dissolved in the process of use, and the residue is easy to damage clothes and not easy to rinse; Laundry liquid can be completely dissolved and quickly dissolved, easy to bleach and wash, and will not harm skin and clothes.
Washing powder is generally strongly alkaline (PH value is above 12), so gloves should be worn when using it to reduce skin irritation. The PH value of laundry detergent is neutral, and the formula is mild and does not hurt hands.
The technical content of laundry detergent is higher, and it is convenient to add various effective ingredients. Washing can make clothes fluffy, soft, smooth and shiny, and has the functions of sterilization and fragrance retention. It is widely accepted by people because of its low comprehensive cost.
The waste liquid produced by washing powder is difficult to degrade in nature (especially sodium alkylbenzene sulfonate with branched chain), which causes water pollution and great damage to ecology. The degradation of laundry detergent is relatively thorough, and the damage to the environment is less.
